Pedro Neto drilled in a 22-yard equaliser as Chelsea and Arsenal played out an entertaining 1-1 draw at Stamford Bridge.
The visitors opened the scoring when Gabriel Martinelli slammed the ball past Blues keeper Robert Sanchez at his near post after collecting a back-post cross from the returning Martin Odegaard.
Chelsea’s leveller was deserved. Neto ran on to an Enzo Fernandez pass before cutting inside and striking a powerful low left-footed shot past David Raya’s dive.
England winger Bukayo Saka limped off late on with an injury as both sides strived to create a winning chance.
Arsenal came closest but Leandro Trossard was unable to divert William Saliba’s cross into the net from six yards, a second before referee Michael Oliver blew for full-time.
The result leaves both teams on 19 points, nine adrift of leaders Liverpool and Arsenal without a win in their past five games in all competitions.
Chelsea have lost once in their past 10 matches and played like a team filled with confidence.
